Boston Whaler Boats

Table 1 shows the color codes of wiring used in Boston Whalers.
"Base" means the color of the wire jacket. "Stripe" means the color
of an identifying stripe in the wire jacket. Color codes
are listed as Base/Stripe, thus "Blk/Brn" means a black wire with a brown stripe.
(It is believed that this color code is a standard used throughout the boat building
industry.) Many electrical items are added after delivery, either by the dealer or the owner,
so it is reasonable to expect that not all wiring found on a boat
will conform to this standard.

OMC Outboard Motors

The following color coded wiring is often seen in outboard motors
manufactured by OMC. This information was developed by Jim Hebert
from factory wiring diagrams. Unfortunately, these diagrams are completely
lacking in annotation. The identification of the circuits involved
was deduced by the author with the assistance of OMC master mechanic
David Zammitt of Lockeman's Boat and Hardware.

Evinrude E-TEC Outboard Motors

The following color coded wiring is often seen in E-TEC outboard motors
manufactured by Evinrude. Where two colors are given the first is the main color of the wire insulation, the second is a color stripe identifier. For example, Yellow/White means a wire with Yellow insulation with a White identifier stripe. This information is also available in a color chart.
